LUBRlCATlNG-"BOX.

SPECIFIEA'I'ION forming part of Letters Patent No. 719,021, datedJanuary 27, 1903.

Application filed December 11, 1901. Serial No. 85,437. (No model.)

To roZZ whom it may concern:

Beit known that l, THOMAS A. MA'rrnnws, a citizen of the United States,residing at New York, in the county of New York and State of New York,have invented certain new and useful Improvements in Lubricating-Boxes,of which the following is a specification.

My invention relates to improvements in devices for furnishing lubricantto open bearings and journals; and the main object of my invention isthe provision of a device which is especially adapted to supplylubricants, lubricating compound, non-fluid oil, and greases to openbearings, journals, and shafts, such as are used in power plants,especially such as paper,te1:tile, and steel plants, bleacheries,lumber-mills, and dye plants.

It has been my especial desire to produce a lubricatingbox which willhave a screen for holding and feeding a lubricant, which lubricant is ofa character that does not melt under 200 Fahrenheit.

To attain the desired objects, the invention consists of a device ofthis character embodying novel features of construction, substantiallyas disclosed herein.

In the accompanying drawings, Figure 1 is a perspective View of the boxwith the lid open. Fig. 2 is a transverse section through the box,screen, and cover at one end of the hinges of the lid. Fig. 3 is a topplan view with the lid open, and at is a view of the screen removed. v

Referring to the drawings, A designates a casing or box, which isprovided with the rolled upper edge B, in which is mounted a rod G, towhich is swingingly attached by means of the two strap-hinges D the lidor cover E. Upon the front and rear lower edges of the casing areprovided the inwardlyprojecting flanges or supporting edges F, which inconnection with the inwardly-projecting segmental flanges G form asupport for the screen. The ends of the casing are provided with thesemicircular cut-awayportions, to which the flanges Gare secured, thusallowing the casing to rest upon and straddle an open bearing or shaft,so that the lubricant can be supplied thereto.

The screen H is semicylindrical in form and has its edges bound by thetwo parallel side pieces or strips J and the two oppositelyarrangedsemicircular end pieces or strips K.

It has been my intention to use a screen which can be made from aperforated sheet of metal or suitable material; but for purposes forwhicha non-fluid oil is employed I have found it desirable to make thisscreen of a metal, mesh or gauze preferably.

It has been customary heretofore in applying solid lubricants to an openjournal to use fibrous matter, such as cotton and woolen yarns or waste,mixed with the lubricant, this being a very unsatisfactory and expensivemanner of lubricating, as a great amount of lubricant is thrown awaywhen the waste is removed from a journal. It has been my intention inproducing this device to dispense with the waste, yarn, and cotton andin their stead use screen material to supply the lubricant, thuspreventing friction and also the great number of hot boxes and fireswhich daily occur through the use of wastes, yarns, and cottons.

My lubricant-holdingbox may be constructed in any shape or form, so asto conform to the shape of the shaft or journal, and the screen to holdthe lubricant may be made of any desirable materialsuch as wire,perforated metal, or other matter--which will screen and conform to theshape of the shaft, these materials all being formed in shape of ascreen, as shown in Fig. 4. By my construction the screen lies closelyto the shaft, so that when the box is filled with the lubricant it willwork through the meshes onto the shaft, the heat and motion of the shafttending to suck or draw the lubricant through the screen and distributeit evenly on the shaft.

The vital point of my invention is the screen, which rests lightly uponthe journal or bearing and which has been more particularly adapted foruse with a class of lubricants known under name and trademark nonfiuidoil, made by the New York and New Jersey Lubricant Company, of which Iam general manager.

What I claim, and desire to secure by Letters Patent, is

1.
